gdal_contour

Create contour lines and polygons from a digital elevation model. More information: https://gdal.org/programs/gdal_contour.html.

• Create a vector dataset with contour lines spread over an 100-meter [i]nterval while [a]ttributing the elevation property as "ele":

gdal_contour -a ele -i 100.0 path/to/input.tif path/to/output.gpkg

• Create a vector dataset with [p]olygons spread over an 100-meter [i]nterval:

gdal_contour -i 100.0 -p path/to/input.tif path/to/output.gpkg
